* Add ADT/IntEqClasses.h as a light-weight implementation of EquivalenceClasses.h.Jakob Stoklund Olesen2010-12-212-0/+108
| | | | | | | | | | This implementation already exists as ConnectedVNInfoEqClasses in LiveInterval.cpp, and it seems to be generally useful to have a light-weight way of forming equivalence classes of small integers. IntEqClasses doesn't allow enumeration of the elements in a class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122293 91177308-0d34-0410-b5e6-96231b3b80d8

* Disallow overlapping inserts, even when inserting the same value.Jakob Stoklund Olesen2010-11-281-97/+9
| | | | | | | | | | | We always disallowed overlapping inserts with different values, and this makes the insertion code smaller and faster. If an overwriting insert is needed, it can be added as a separate method that trims any existing intervals before inserting. The immediate use cases for IntervalMap don't need this - they only use disjoint insertions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120264 91177308-0d34-0410-b5e6-96231b3b80d8
